Learn How to Win Material: Ruy Lopez Tactic
This Ruy Lopez Cozio Defense puzzle is a classic middlegame example of tactical refutation in a sharp but seemingly balanced position. White has active pieces and pressure, but Black can exploit a loose bishop and the alignment of major pieces to win material. The key idea is to look for forcing moves that change the tactical balance immediately, especially when a defended-looking piece is actually vulnerable to a capture sequence.
